The Lowdown
Alright folks, Rusty here. Let’s talk about what’s on offer for the next couple of weeks.
Overall, it’s a pretty quiet run for Costeño Beach. We’ve got a consistent, mellow NE swell hanging around, but the wave quality is mostly ordinary. The wind is a bit of a pest for much of the time, though there are a few windows where things glass off nicely. The real standout is a couple of afternoons where the ocean just lays down flat and clean.
The first real chance to get something decent is on Thursday, the 10th of September. The morning is a bit rough with a cross-on breeze, but the afternoon turns glassy. You’re looking at a 5 ft swell from the NE, with a period of 7 seconds. The wave energy is moderate at 248, so it’s not a powerhouse, but with the wind dropping off to glass, it’ll be clean. This is a good time for a beginner to get out and have a fun, uncrowded session.
Saturday, the 12th of September, is another one to circle. The morning is a bit bumpy with a cross-on wind, but the afternoon is the true highlight of the whole forecast. The wind goes completely calm, glassy as can be. The swell is 6 ft from the NE with an 8-second period, and the combined energy is a solid 423. It’s the best wave size and cleanest conditions of the whole period. For a beginner-friendly spot, this is about as good as it gets.
The following Sunday, the 13th of September, also has a glassy afternoon with a 5 ft NE swell, so keep that in mind if you miss Saturday.
After that, things settle back into a pattern of small, ordinary, and often bumpy surf. The water temperature is a warm 84°, which is about normal for this time of year, so no surprises there.
The gaps between the good sessions are a few days at a time, so it’s not a total washout, but you’ll need to pick your moments. The long-range stuff around the 19th and 22nd of September shows some glassy mornings with small 4 ft waves, but nothing that really stands out as a must-surf.
So, wrap it up: the best on offer is definitely the glassy afternoons on Thursday the 10th and Saturday the 12th of September. Saturday is the pick of the bunch for size and conditions.
Rusty.

Our star ratings will help here and of course you will also find the usual wave height and period predictions on our surf forecasts as well as a full break down of the swell components under our advanced users option (to reveal that, click the little Einstein character under the tide times).
Further information to help with frequently asked questions about our surf forecast for Costeño Beach may be found under the help tab on the top menu and also by moving your mouse over the question marks on the surf forecast table itself.
